,Chapter 1 — The History of Anesthesia
1. Which plant extract served as a common surgical soporific before the discovery of
ether?
A. Willow bark infusion
B. Mandrake root extract
C. Digitalis leaf powder
D. Cinchona tree tincture
Answer: B
Rationale: Mandrake root containing scopolamine and hyoscyamine was historically steeped in
wine to induce surgical sleep. Ancient and medieval practitioners relied on these
anticholinergic alkaloids for primitive sedation. The formulation fell out of favor due to
unpredictable potency and severe toxicity.
Keywords: history, soporifics, mandrake
2. What physiological gas did Henry Hill Hickman use to induce surgical insensibility in
animals?
A. Inhaled carbon monoxide
B. Compressed nitrous oxide
C. Aerosolized ethyl ether
D. Inhaled carbon dioxide
Answer: D
Rationale: Henry Hill Hickman conducted animal experiments in the 1820s inducing suspended
animation with carbon dioxide. He demonstrated painless surgical interventions in small
animals by exploiting the gas's asphyxial and anesthetic effects. Hickman's experimental
findings were dismissed by contemporary scientific academies in Britain and France.
Keywords: Henry Hill Hickman, carbon dioxide, early anesthesia
3. What surgical procedure did Crawford Long perform under sulfuric ether in March 1842?
A. Excision of a neck tumor
B. Amputation of a forearm
, C. Extraction of a molar tooth
D. Repair of an inguinal hernia
Answer: A
Rationale: Crawford Long administered sulfuric ether to James Venable in Jefferson, Georgia,
in March 1842 to resect two neck tumors. Long documented the painless operations in his
ledgers but delayed formal publication of his results until 1849. This delay prevented him from
receiving immediate universal credit for the clinical introduction of surgical anesthesia.
Keywords: Crawford Long, ether, history
4. Which anesthetic gas did Horace Wells demonstrate at Massachusetts General Hospital
in 1845?
A. Sulfuric ether vapor
B. Liquid chloroform drop
C. Inhaled nitrous oxide
D. Concentrated ethyl chloride
Answer: C
Rationale: Dentist Horace Wells conducted a public demonstration of dental extraction under
nitrous oxide at Massachusetts General Hospital in January 1845. The patient cried out during
tooth removal because the gas bag was withdrawn prematurely, leading spectators to deride
the demonstration as fraudulent. Wells nevertheless correctly recognized the profound
analgesic potential of inhaled nitrous oxide.
Keywords: Horace Wells, nitrous oxide, demonstration
5. Who performed the surgical resection during William Morton's public ether
demonstration in 1846?
A. Henry Jacob Bigelow
B. John Collins Warren
C. Oliver Wendell Holmes
D. Charles Thomas Jackson
Answer: B
Rationale: Senior surgeon John Collins Warren excised a vascular submandibular tumor from
Gilbert Abbott on October 16, 1846, at Massachusetts General Hospital. After completing the
,painless procedure under Morton's inhaled ether vapor, Warren uttered his famous declaration
that the demonstration was no humbug. This pivotal event established inhalational anesthesia
as an authentic clinical practice.
Keywords: William Morton, John Collins Warren, Ether Dome
6. Who introduced chloroform into clinical obstetric practice in Edinburgh in 1847?
A. James Blundell
B. William Smellie
C. Thomas Wakley
D. James Young Simpson
Answer: D
Rationale: James Young Simpson discovered the anesthetic properties of chloroform during
self-experimentation and began administering it for labor pain in November 1847. He
vigorously defended the practice against contemporary theological and medical critics who
opposed labor analgesia. Simpson's advocacy rapidly popularized chloroform as an alternative
to diethyl ether in Europe.
Keywords: James Young Simpson, chloroform, office-based anesthesia
7. Who administered chloroform to Queen Victoria for the delivery of Prince Leopold in
1853?
A. John Snow
B. Joseph Clover
C. Francis Sibson
D. Edward Lawrie
Answer: A
Rationale: John Snow administered inhalational chloroform to Queen Victoria in April 1853
during the birth of Prince Leopold, legitimizing obstetric analgesia worldwide. Snow utilized a
calibrated hand-held inhaler to maintain light, titrated surgical anesthesia without loss of
uterine contractions. The celebrated royal administration was popularized as anesthesia à la
reine across Britain.
Keywords: John Snow, Queen Victoria, chloroform
, 8. Which surgeon performed the first documented elective oral endotracheal intubation in
1880?
A. Joseph O'Dwyer
B. Franz Kuhn
C. William Macewen
D. Friedrich Trendelenburg
Answer: C
Rationale: Scottish surgeon William Macewen passed flexible metal and rubber tubes through
the oral cavity into the trachea by tactile guidance in 1880. He demonstrated that oral tracheal
intubation reliably protected the lower airway from aspiration during tongue surgery.
Macewen's work laid the conceptual and technical foundation for elective modern tracheal
intubation.
Keywords: William Macewen, intubation, airway history
9. What major airway technique did Ivan Magill introduce for facial reconstruction surgery?
A. Rigid bronchoscope lighting
B. Blind nasal tracheal intubation
C. Cuffed supraglottic airways
D. Fiberoptic intubating stylets
Answer: B
Rationale: Ivan Magill and Stanley Rowbotham developed wide-bore rubber endotracheal
tubes and blind nasal intubation techniques for soldiers with facial trauma. Magill also
designed specialized angled forceps to direct the tube tip into the glottic aperture under direct
laryngoscopic vision. His innovations revolutionized airway management during oral and
plastic maxillofacial procedures.
Keywords: Ivan Magill, nasal intubation, airway history
10. Where is the tip of a curved Macintosh laryngoscope blade placed to expose the vocal
cords?
A. Into the space of the vallecula
B. Directly beneath the laryngeal surface
C. Across the dorsal pharyngeal mucosa
D. Beneath the posterior cricoid lamina
,Answer: A
Rationale: Robert Macintosh designed his curved blade in 1943 to seat within the vallecula
anterior to the epiglottis. Upward traction on the hypoepiglottic ligament indirectly elevates the
epiglottis to visualize the vocal cords without touching its sensitive posterior surface. This
indirect elevation minimizes cardiovascular reflexes and reduces direct laryngeal tissue
trauma.
Keywords: Macintosh blade, vallecula, laryngoscopy
11. Who developed the to-and-fro carbon dioxide absorption canister in 1923?
A. Dennis Jackson
B. Arthur Guedel
C. Brian Sword
D. Ralph Waters
Answer: D
Rationale: Ralph Waters constructed the to-and-fro carbon dioxide absorption canister
containing soda lime for clinical closed-circuit anesthesia in 1923. His apparatus allowed
efficient rebreathing of anesthetic vapors and oxygen while chemically neutralizing expired
carbon dioxide. Waters' clinical trials established the physiological feasibility of chemical
carbon dioxide scrubbers in breathing circuits.
Keywords: Ralph Waters, carbon dioxide absorption, breathing circuit
12. What operating principle defined the Copper Kettle vaporizer designed by Lucien
Morris?
A. Electronic thermal feedback coils
B. Pressurized variable-area flow valves
C. Measured bubble-through gas bypass
D. Electrically heated vapor injection nozzles
Answer: C
Rationale: Lucien Morris introduced the Copper Kettle in 1952, using heavy copper
construction to provide high heat capacity and thermal conductivity. A measured oxygen flow
stream bubbled directly through the liquid anesthetic agent to generate a saturated vapor that
joined the main gas flow. This design allowed precise, reproducible volatile anesthetic delivery
despite ambient temperature fluctuations.
, Keywords: Copper Kettle, vaporizer, Lucien Morris
13. What monitoring modality was first adapted for continuous intraoperative cardiac rhythm
surveillance in the 1930s?
A. Phonocardiography
B. Electrocardiography
C. Ballistocardiography
D. Echocardiography
Answer: B
Rationale: The integration of continuous electrocardiography into operating rooms in the 1930s
permitted real-time detection of surgical arrhythmias and myocardial ischemia. Pioneered by
early clinical investigators, visual oscilloscope displays replaced intermittent pulse palpation
during complex thoracic cases. Electrocardiography subsequently became universally
mandated in global standards for basic intraoperative monitoring.
Keywords: electrocardiography, monitoring milestones, arrhythmia
14. Who developed the operational principles of dual-wavelength pulse oximetry in 1972?
A. Leland Clark
B. John Severinghaus
C. Michael Sismanis
D. Takuo Aoyagi
Answer: D
Rationale: Japanese bioengineer Takuo Aoyagi recognized in 1972 that arterial oxygen
saturation could be computed from the ratio of pulsatile red and infrared light absorption. By
isolating the time-varying arterial waveform from static tissue and venous absorption, Aoyagi
created the foundational physics of pulse oximetry. His invention dramatically reduced
intraoperative hypoxic brain injury and anesthesia-related mortality.
Keywords: Takuo Aoyagi, pulse oximetry, monitoring history
15. Which document established the first institutional mandate for intraoperative
capnography in 1985?
A. Harvard Monitoring Standards
B. The Helsinki Declaration Standards
